The server will use fandango.linos module to monitorize some OS processes.
For each process detailed in the ProcessList property (e.g. notifd) the device will generate several dynamic attributes: * notifd_pid: * notifd_mem: * notifd_cpu: The Update() command will force the update of this variables. This device server will be used to monitorize notifd issues in several control machines and trigger Alarms/Archiving if needed.
